To all whom it may concern:

' Cleaning Apparatus, of which the following Be it known that I, ROBERT P. SWEENY,

.a citizen of the United States, residing at Union, in the county of Union and State of South Carolina, have invented certain new and useful Improvements 1n Air-Inductionis a specification. v

. This invention relates to air induction cleaning apparatus for cleaning industrial plants, houses, or other places where lint,

the framework of the apparatus may be. employed and 'whereby the bag may be easg ily attached to and disconnected from the and reaches the expanding portion of saidthis point.

condition. waste is drawn in bythe suction end of my machine. x I r Another object, of this invention is to open up the cotton waste, etc., picked up by the cleaner and to put this waste in a fluify I have found that when this Venturi-.tube, it passes on through the same tube, and this expanding portion allows the air to expand; this-has an expanding effect on the fibrous material of the waste that. is being conveyed; this also serves to flulf up and bloom up the fibrous material and to -pull the individual fibres apart, the fibrous material being completely impregnated with the air which is III'PI'OCBSS of expanding at This renders. the material of much higher manufacturing'value in the after process of manufacture. It also rendersthe impurities contained in thefibrous material more readily removable. I

' Another objectof the invention is to so arrange'the Venturi tube, waste collectin" ugal motion of the air tdgetherwith the downward pressure of air to distribute and pack the wastemate'rial in the waste bag, thereby greatly incmasing the ca au'ity of the waste bag.

a Another object of the invention is to so mount the apparatus that it can be conveniently pushed in sharp turns around the machinery being cleaned. Another object of the invention isto so construct the apparatus framethat it will have the maximum strength and endurance for the. work in which it is to be-used. Another object of the invention is to provide for quick attachment and detachment of-the apparatus from the waste collecting hose or the source of air. supply.

Another object'of the invention is to so arrange the Venturi tube parts of the apparatus as to get the maximum efiiciency from the air pressure employed.

Another object of the invention is to so construct the parts of the framing as to re- ;lieve strains on the pipe connections.

Another object ofv the invention isfto pro- 'vide a framework relatively long compared with its width so that it can pass in narrow passages" between the machines being' cleaned. q,

Another object of the inventionis to regulate the speed of the passage of the air through the machine by properly regulating the ressure at the discharge. orifice.

With the foregoing objects outlined and other objects in view which will appear as the description proceeds, the invention con- .sists in the novel features hereinafter described in detail, illustratedin the accompanying; drawings and more particularly pointed out in the a ppended claims. Referring to the rawings:.

Figure 1 represents a side. view of the apparatus with part of the suction hose and nozzle.

- Fig. 1 is a. rear view of the machine with v the suction 'hose and couplings and nozzle omitted. v

Fig. 2 is a top plan view .of the waste collecting cylinder with the top removed Show,

ing the entrance therein of the air and waste tube and its. coiled construction.

Fig. 3 is a side elevation of the mechanism shown in Fig. 2.

' }Figs., 4, 5,6 and 7 are sectional views of chamber and parts as to employ the cent-ri t whereby the top may beeasily taken off or within the cylindrical chamber endng ap-.

proximately under the end of an inclined shelf 5, within the chamber 1. The waste laden air passing through the pipe 4 and coiled part 8 is delivered under the inclined shelf 5 which, on account of its downwardly inclined portion has a tendency to direct the waste particles as they leavethe pipe towards the bottom of the cylinder 1 into the waste bag 9 through the pores of which the air escapes and at the bottom and on the sides of which the waste settles.

On the end of inclined shelf 5 is placed a deflector 5' which is inclined downwardly at a sharper angle than shelf 5. The incoming air and waste strikes this deflector and is quickly thrown to the bottom of the waste bag thereby packing the same in the bag. The centrifugal motion of the air causes the waste to be evenly distributed around the bag. The deflector also prevents too much centrifugal motion. The waste collecting chamber also serves as an expansion chamber for the incoming a1r and on account of its tight top, a downward pressure of air further causes the waste to be packed in the bag.

The pipe section 4 may be slightly larger at its end where it enters the waste chamber 1 than it is at. the other end where it is attached to another pipe section 10 also preferably metal which may be flared slightly from its end attached to the section 4, to its other end attached to an elbow 11 preferably of metal. The approximate relative sizes which admit of variation of different cross sections of this section 10 are illustrated respectively in Figs. 4 and 5, and the size of the section 4 a proximately relative to that of section 10 is illustrated in Figs. (Sand 5. These pipe sections are The end of the pipe section maybe preferably rigidly held together and to the waste collecting chamber, the elbow section being rigidly supported on the framework.

At the end of pipe section 10 there is provided a part 12 (Fig. 5) through which extends a hole 13. The interior edge of this hole may be slightly above the bottom of pipe section 4 as shown in Fig. 3 and through the hole v13 passes a nozzle 14 of a compressed air pipe 15, preferably of metal. s lit as shown in Fig. 5 and the opposite 551a portions held together around the nozzle 14 by a screw, as shown. The nozzle 14 is coupled to the pipe 15 by ordinary pipe couplings and may be elevated slightly above the bottom of the pipe section 4 and may be upwardly inclined to said bottom as shown in Fig. 3 so that when the compressed air passes from the nozzle it may be upwardly inclined to better draw the air and material being conveyed through the pipe section 10, elbow 11 and air hose 16 and suction nozzle. It will be noted in Fig.1 that the sections 10 and 4 are given a slight inclination downwardly so that any water of condensation resulting from the sudden expansion of the air as it comes through the nozzle 14 will trickle down the pipe section 4 and escape at the end of the pipe to prevent the water from remaining in the pipe and collecting the dust and lint as it is brought in through the hose 16. However, there is provided a clean-out hole 17 in the elbow 11 as shown in Figs. 1 and 2 which may be opened and the elbow 11 and pipe sections 10 and 4 cleaned of any accumulation of lint or dust.

The elbow 11 is rigidly supported by brace rods 18, 18' firmly attached to 'brackets 19 and 19' which in turn'are attached to a band 20 passing around the waste chamber '1. The ends of this band are held by bolts 21 which may be loosened and the chamber 1 removed from the framing of the machine when desired.

Extending'from the bracket 19 is a brace rod 22 slightly inclined as shown, its lower end being firmly secured to the truck 23, and a vertical rod 24 extends from the truck 23 and is attached to the bracket 19 as shown -in-Fig. 1, the similar 'bracket 19' Fig.1

being attached to the other side ofthe band 20. From this bracket 19' a vertical rod 24 extends to the truck23. Passing from the rods 24 and 24' are brace rods 25 and 26,

the rod 26 extending beyond and around be cleaned. A similar brace rod ito 22 is attached to bracket 19- Connected to the compressed air pipe 15 is a gage 29 and the pipe 26' protects the connection between the gage and the pipe from coming in contact with projections or Walls as indicated in Fig. 1 when the hose 16 is disconnected from the cleaning machine. The gage 29 will indicate to the machine attendant the pressure in-the com-' pressed air pipe 15. This pressure is regulated by an ordinary pressure regulating and reducing valve 30 and the lower part of the machine and this regulating valve is prevented from coming in cont-act with the machine being cleaned or a post or wall by the brace rod 25 as shown in Fig. 1.

9 the front of the truck so that the .bag can be the compressed air passage, and any water 1 yvhich might collect in the compressed air Within the horizontal portion ef the compressed air passage 32 may be interposed an ordinary spring loaded'valve 32' for cutting off the supply of compressed air between the horizontal portion 32 of the compressed air passage and the flexible compressed air hose,

the end 33 of which is shown in Fig. 1. This hose is connected to the horizontal air passage 32 by an ordinary quick-change hose coupling 34, Fig. 1, whereby the waste collecting machine may be quickly separated from the source of compressed air. This source of compressed air may be a pipe, a

pump, or an ordinary compressed air tank.

The entire machine is supported on the truck 23 having wheels 35-35 with their axes passing through projections 36- 36' on the lower edge of the truck. A third wheel 37 is swiveled to the truck frame thus enabling the machine to be suddenly turned in any direction and pushed about between the machines, etc. to be cleaned. A stop 38 5n the front of the truck prevents tipping of the machine forward too far.

compressed air pipe is supported on a board 39 bolted to the uprights 24 and 24 as shown in Fig. 1.

It will be noticed that the framework of the apparatus is considerably narrower than it is long so that it can go along narrow passageways between the machines, etc. be- 111g cleaned. The truck platform 23 is dishshaped to receive the bottom of the bag, the sides 40 of the platform being cut away at slid off the truck without raising the same. Particular attention is drawn to the way the waste chamber overhangs the truck and the way side braces 22 are placed so as not to interfere in any way with the hands of the machineoperator in putting on and taking off the waste bags.

The bag is conveniently attached to-the waste chamber 1 by a cord 41 which is threaded through the hemmed part of the top of the bag and rests on a flange 42 projecting from the bottom of the waste chamber 1. By loosening the cord 41 the mouth of the bag may be opened sufliciently to pass over the flange 42 and by drawing the cord The regulating valve and horizontal portion of thev 41 the mouth of the bag may be closed and the collected waste, lintetc. conveniently removed from the truck platform and an empty bag put in its place.

' The two ends of the draw cord on the bag may be passed through a cord fastener to automatically hold the cord tight at any desired point. The cord fastener bein part of a bag equipment and of an or inary type is not shown in the drawings as the cord is shown cut away in Fig. 1 to show flange 42.

The hose 16 may be the ordinary flexible air suction hose made of rubber or fabric with a wire coil around it of any othert and the compressed air hose 33 may also e of the usual construction.

As indicated in Figs. 1 and 1 the framin of the waste collecting machine may be ma e of ordinary iron tubing coupled .where required so as to stand any ordinary strain as the waste collecting apparatus is moved around from place to place, a tubular rod 43, Fig. 1 preventing any sidewise give of the framing joints and the'rods 22 preventing strain on the joints and brackets in a direction lengthwise of the frame structure. The board 39 and another board 39" near the top of the framework bolted to the upright rods increases the rigidity of t frame structure as a whole, and serve as supports for parts of the air induction appara-tus.

section of pipe 50 by means of a pin and an inclined slot in a coupling 57 and to the 'pipe 50 is connected a nozzle slightly flared at its end and connected to the pipe 50 by a pin and inclined slot-in-the coupling 52. This nozzle is bent as shown at 53 and again as shown at 56, the bent end section being-connected to a section 54 by a pinand inclined slot' in a coupling 55. I have found the bent and flared nozzle a most convenient arrangement'in reaching around obstructions and in collecting waste, dust, etc., on the under surfaces of machine parts. By

turning the bent part of the nozzle the flared end may be brought over surfaces at various inclinations to the operator.
